Let me tell you what I did in our first full time rig, which was a 26ft travel trailer with the same issue. Finding chairs that have a removable base, but that would still swivel was the issue. I found some patio chairs that were super comfy swivel rockers, and cut the legs to take the platform off. I bolted the remaining swivel base to a plywood platform that I built over the water tank that was under the couch, because the existing platform was not stiff enough. This I covered with carpet. The worst issue was the cold steel arms, which we covered with seat belt pads. Sorry, this was way before digital & I have no photos.
